     Cow-pox, or, as I have proposed to name them, the Vacciola scutellata and leprosa, as nothing within my sphere of observation has tended to retard the progress of the new inoculation so much as the difficulty which inexperienced inoculators find in learning to distinguish the two diseases, which unhappily the vacciolous virus is capable of producing.

   • 1804, Frederic Thackeray, “Letters to the Editor”, in The Medical and Physical Journal, volume 12, page 331:

     In the year 1801, a gentleman inoculated his own two boys and two of his servants with vacciolous matter, that was sent by Dr. Pearson; on the eighth, tenth, and twelfth days I Saw their arms, and was well satisfied that vacciolation had taken place.

     The object of this society is the total extermination of the small pox, by substituting in its stead the vacciolous.
